[Dovecot] inotify max_user instances

[Charles Marcus]

Hello,

Timo, last year when you remoted into our server and performed the 
migration from courier-imap, we ran into this issue, and you solved it 
by doing:

echo 1024 > /proc/sys/fs/inotify/max_user_instances

Then you said you were going to solve this permanently by changing the 
init script...

Here is what you said (this is from the skype chat):

[2012-06-04 10:40:43 AM] timosirainen: probably put to dovecot init 
script or something

I guess I could manually modify my init script, but I'm clueless as to 
where.how.

The current (gentoo) init script is:
